On my walk to...

On my walk to the subway this morning, it occurred to me that New York City (among the multitude of things you can say about it) is sorta like an onion. The City is like an onion in the way that research questions are like onions - you peel back a layer of questions, observations, issues, whatever's on the surface, and there's another new layer beneath it, so on and so on. Each morning I walk almost the exact same route, and on the days I really watch, another layer of the street peels back to reveal something new.On rainy days, however, New York is not just any onion. It's a smelly wet onion. Yuck!
